iMPRovED' MEAT-CRUSHERfN A Specification forming part f Letters Patent No. 48.072, dated June 6,"186-5.

` clare that the following is a full, clear, and exact description "thereof, which will enable those skilledin'f'the art to make and usethe same, reference beinghad to the accompanying draw- Y ings, forming whichpart of this specification, in

Figure l is a front elevation of my inven `tion; Fig. 2, a transverse-vertical section of thesame, takeninlthalinem w, Fig, 2.

Similar letters. of reference indicate corre` sponding parts. v This invention relates to a new and improved machine for crushing meat, breaking the fibers l thereof, so as to render it tender and more desirable for the table than it otherwise would be. The invent-ion consists in the employment or use of cylindersor rollersplaced in a suitable frame,` the upper roller 'being mounted in sliding boxes provided with guide-rods and spiral springs tending to press the rollers in Contact, y while thelower roller, to.whieh the crank is applied, rotatesiu iiXed bearings. Y y A'represents a rectangular upright frame,

incoznposed of two upright side pieces, a a, con'- nected at their upper and lower ends by cross lower one, C, lhaving its bearings in the side pieces, a a, of the frame A, with a crank, D,

at one end of its shaft c for the convenience oi'` turning it. The upper roller, C', has its bearings 'in slides E'E,which are itted in grooves d in the inner surfaces-of the side pieces, a o, and have vertical rods F attached to them, one to each, which rods extend up through the Atop cross-har, Ab-, ofthe frame A, andare allowed to slide or work freely therein. 0n

each rod C a spiral spring, H, is placed, 4the springs have a tendency to' keep the'upper` roller, C, pressed down'in contact with the lower one, C. The rollers C C arefbot'h .corrugated, the upper one,-C', by means-ot longi.

tu'dinal grooves e, and the lower oneC,1byA similar grooves,e,and circumferential grooves f, the lastv-naintd grooves having tooth-like projections on C. operated upon is passed 'between' the rollers .C C', the lower one, C, lot-ingturnedv through vthe medium ofthe crank and subjected to a greater Or less degree of pressure, according to )the strength ot thesprings H,`which should be sufficient 'to break' the bers of the meat. Thus by this simple devicemeat ma)` be crushed 'and madeteuder with thegreatest facility and without the laborious work and noise attending the usual pounding operation. i

cast-iron, and the the frame also, if desired;- `but I do not conline myself tolany, particular material. i

` I claim as new and desire to secure by Letters Patent- Y Theconibination of the'roller C, rotating' iii ijXed bearings, and provided with a crank, D,

the roller C. mounted in sliding boxes E E. the;
